Thanks for the explanation.
"...eliminating ANY type of Noise or Distortion would be a good thing, right?"
Most certainly sir.

Lowering the noise floor
I am coming to the conclusion that success in home audio reproduction is largely about lowering the noise floor. There are so many different types of “noise”, from so many different sources, that we only really “hear” by their absence.
Those components, cables, accessories and tweaks that SUCCEED at lowering the noise floor, can, and do, dramatically increase sound quality. Sometimes the type of “noise” dealt with is controversial, or not (yet) widely recognized as being a problem. Sometimes the explanation of how a product works is dubious. Sometimes the way it is marketed reeks of “snake oil”. Sometimes the reviews singing its praises go over the top. While these things will certainly put off some prospective purchasers, they do not negate the audible results that are there for anyone open to hearing them.

By getting off the grid I avoid all the ills associated with the grid, and all the ills associated with cables, fuses, and the other stuff I already mentioned. Trust me, it’s audible, even on my modest system. I mean, I still can tweak it, right. I use only treated batteries and everything has been quasi cryod at a minimum and everything is mechanically isolated. Wonder why professional rock bands don't do this. |
tommylion "Lowering the noise floor" 90% of systems these days have enough gain from the source and in the poweramp so a passive pre can be used, this get’s rid of a large source of noise, the "active preamp". Remember what nelson pass said: Nelson Pass, "We’ve got lots of gain in our electronics. More gain than some of us need or want. At least 10 db more. Think of it this way: If you are running your volume control down around 9 o’clock, you are actually throwing away signal level so that a subsequent gain stage can make it back up. Routinely DIYers opt to make themselves a “passive preamp” - just an input selector and a volume control. What could be better? Hardly any noise or distortion added by these simple passive parts. No feedback, no worrying about what type of capacitors – just musical perfection. And yet there are guys out there who don’t care for the result. “It sucks the life out of the music”, is a commonly heard refrain (really - I’m being serious here!). Maybe they are reacting psychologically to the need to turn the volume control up compared to an active preamp." Cheers George |
